SpaceX just launched more satellites in a month than history has ever seen. But that’s bad news for astronomers.

SpaceX’s newest satellites sport sun visors — an effort to reduce their brightness in the night sky and their impact on astronomers’ telescopes.

The emergence of artificial intelligence and machine learning techniques is changing the world dramatically with novel applications such as internet of things, autonomous vehicles, real-time imaging processing and big data analytics in healthcare. In 2020, the global data volume is estimated to reach 44 Zettabytes, and it will continue to grow beyond the current capacity of computing and storage devices. At the same time, the related electricity consumption will increase 15 times by 2030, swallowing 8% of the global energy demand. Therefore, reducing energy consumption and increasing speed of information storage technology is in urgent need.

Berkeley researchers led by HKU President Professor Xiang Zhang when he was in Berkeley, in collaboration with Professor Aaron Lindenberg’s team at Stanford University, invented a new data storage method: They make odd numbered layers slide relative to even-number layers in tungsten ditelluride, which is only 3nm thick. The arrangement of these atomic layers represents 0 and 1 for data storage. These researchers creatively make use of quantum geometry: Berry curvature, to read information out. Therefore, this material platform works ideally for memory, with independent ‘write’ and ‘read’ operation. The energy consumption using this novel data storage method can be over 100 times less than the traditional method.

This work is a conceptual innovation for non-volatile storage types and can potentially bring technological revolution. For the first time, the researchers prove that two-dimensional semi-metals, going beyond traditional silicon material, can be used for information storage and reading. This work was published in the latest issue of the journal Nature Physics^[1]. Compared with the existing non-volatile (NVW) memory, this new material platform is expected to increase storage speed by two orders and decrease energy cost by three orders, and it can greatly facilitate the realization of emerging in-memory computing and neural network computing.

The cyberdelic extravaganza is online for the first time because of the pandemic. But maybe that’s not as strange as it might seem.

Xanadu, a photonic quantum computing company, announced today the release of the world’s first publicly available photonic quantum cloud platform, according to a press release. Developers can now access Xanadu’s gate-based photonic quantum processors, in 8, 12, and soon 24-qubit machines.

Photonics based quantum computers have many advantages over older platforms. Xanadu’s quantum processors operate at room temperature. They can easily integrate into existing fiber optic-based telecommunication infrastructure, enabling a future where quantum computers are networked. It also offers great scalability supporting fault tolerance, owing to robust error-resistant physical qubits and flexibility in designing error correction codes. Xanadu’s unique type of qubit is based on squeezed states – a special type of light generated by our own chip-integrated silicon photonic devices.

“We believe that photonics offers the most viable approach towards universal fault-tolerant quantum computing with Xanadu’s ability to network a large number of quantum processors together. We are excited to provide this ecosystem, a world-first for both quantum and classical photonics,” said Christian Weedbrook, Xanadu Founder and CEO. “Our architecture is new, designed to scale-up like the Internet versus traditional mainframe-like approaches to quantum computing.”

SpaceX gave an update on early tests of its Starlink satellite internet network, which showed speeds capable of playing online video games and streaming movies.

Starlink is the ambitious plan by Elon Musk’s company to build an interconnected network of about 12,000 small satellites in low Earth orbit. To date, SpaceX has launched about 650 of its version 1.0 satellites and is currently building a system of ground stations and user terminals to connect consumers directly to its network.

The company confirmed during the webcast of its latest launch on Monday that employees have been testing Starlink’s latency and download speeds, key measures for an internet service provider. SpaceX senior certification engineer Kate Tice said that the initial results of those tests “have been good.”

New research shows how the next generation of ultra-secure communication could be possible with existing infrastructure.

Capable of connecting eight or more users across distances of 17 kilometers, the demonstration is another milestone toward developing a fully quantum Internet.
